An Overview of Sulfur Extended Asphalt Usage

The unique properties of sulfur, both alone and when blended with asphalt, have also shown potential for use in recycling old bituminous pavements. This paper attempts to put into perspective the state of the art in design, preparation, placement, and performance evaluation of sulfur-extended asphalt (SEA) pavement mixtures.

0.3% sulfur has a certain effect on the rutting resistance of high-cured crumb rubber hybrid binder before aging, while 0.1% sulfur and 0.2% sulfur have little effect on the rutting resistance. Sulfur can reduce the hardening degree of high-cured crumb rubber hybrid binder after PAV aging, and the improvement effect of HC_3SBS_0.3S is obvious.

EVALUATION OF MIXTURE PERFORMANCE AND STRUCTURAL

The use of sulfur as an asphalt mixture modifying agent (known as SEA, or sulfur-extended asphalt) was originally tried in the 1970s and continued into the 1980s. The added sulfur was used both as a binder extender (replacing a percentage of the asphalt binder) and to modify the properties of the resulting asphalt mixture.
